To all whom it may concer-1e.- A

Be it known that I, WILL F. HOYT, a citizen of the United States, residing at the cityof Dowagiac, in the county of Cass and State of Michigan, have invented a certain new and useful Disk Drill, of which the following is a specification.

This invention relates to improvements in grain drills, and more particularly to improvements in grainfdrills using disks as furrow markers or openers, though certain parts of the device are capable of utilization in other relations.

The objects of -this invention are, first, to

simplify the construction of grain-drills generally second,to provide an improved springpressure means for disk grain-drills; third, to provide improved means of varying the adjustment of pressure-springs on' grain-drills generally; fourth, to provide an improved construction of scraper for the disks of graindrills; fifth, to provide an improved yoke for joining a pair of graindrill disks together, and, sixth, to provide an improved construction of conduit or boot for use in connection witha disk furrow-opener in a grain-drill.

Further minor objects will appear definitely in the detailed description to follow.

I accomplish these objects of my invention by the devices and means described in this specification.

The invention is deiinitely pointed out in the claims. i

The portions of the structure to which my invention relates are fully illustrated inthe accompanying drawings,forminga partof this specification, in which` Y Figure 1 is a detail vertical sectional view from front to rear of a grain-drill embodying the features of my invention, taken on a line corresponding to line l 1 of Fig. 2. Fig. 2 is a detail plan view of a portion of the structure appearing in Fig. 1, a part of the seed-hopper being broken away to show the details of construction of the disk'and hangers beneath. Fig. 3 is an enlarged detail sectional elevation of one of the disks and hangers, taken on a line corresponding to line 3 3 of Fig. 2. Fig. 4 is an enlarged detail elevation of one of the seed-boots, conduits, and hangers and its con- :nections to the drag-bar of one of the disks.

`by dotted lines.

Fig. 5 is a plan View of the adj listing-bracket for attaching the forward ends of the pressurespring to the drag-bar. Fig. 6 is a side view of the same with the adjacent parts indicated A Fig. '7 is an end elevation of oneof the cross-braces K. Fig. S is a detail plan view ofthe end of the same. Fig. 9 is a sectional View through the scraper for the disk, taken on a line corresponding to lines 9 9 of Figs. 1 and 10. Fig. 10 is an inside detail elevationalview of the said scraper.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the usual mainframe of the drill. A' are the carrying-wheels for the same, and Al the seed-hopper, all of which are in the usual form.

To the front bar of the frame are secured suitable hangers, to which are pivoted the drag-bars C C. A pair of drag-bars C C go ywith eachpair of oppositely-facing concaveconvex disksB. The drag-bars are supported on oppositely-projecting pins C and are retained on the same by the brace K, bolted between them; The drag-bars C are secured together at their lower ends by a yoke E.

` The disk-hangers and boots F are made integral and arecontinued down and open below and to the rear of the trunnion carrying the disk, as clearly appears in Figs. 3 and 4.

i The opening h from theconduit is close to the disk and within the furrow formed by the same. The inner wall F' of the conduit extends lwell down toward the bottom to protect the conduit from becoming clogged by "any soil adhering to the disk and to insure theeven distribution and discharge of the grain into the bottom of the furrow. The opening of the conduit comes close down to the furrow, that the grain will not be disturbed by the machine passing over stubble or other obstructions. The convex sides of the disks are placed toward eachother, and

the hanger-plates,with theirV boots, are placed within the same, and they are secured to the drag-bars C by the bolts which secure the drag-bars to the yoke E. On the inner sides IOO of the upperend ,of the beets @here are .Slight lateral projections n .for engaging'over the spring press-rods D- when they are elevated to raise the disks from the ground in transporting the machine. The rear en ds of the pressrodstwo in number for each pair of disksare secured by suitable link'connection's I-I to arms I-I on the usual rock-Shaft 'G to the rear of the machine, which rock-shaft is controlled by the usual lever G', engaging notched segment' G", all of which adjusting means are well known and' in common use and need no further deseriptien here., AThe .Spring pressrods are secured at Vthe hforward endv bythe adjustable bracket J, having a notched ear J below. The springs D at their forward ends are bent ydownwardly and rearwardly at D',`a nd the extreme eind' is turned at fright 'angiesJ at D "tofp'rm an engaging stud." The Dreeke@ J ie retefi'ned by the belt through the end of the brace K and is adjustable aforward and. beek by' 'the belt enteringe Suitableslot d, as clearly appears in Fig.` 6J By adjusting theplate tliestudy D can' be caused to rest either i`n the neteh et e' er at e, time varying thfe'tens'ion ofthe spring D, venabling the applieeten'ef Streng epring-pleeeiu'e .te the (lieke Ormekingthe pressure very light and, .in fact, restrain or support the disks when their' eene to' ge tele deep: The end ef the bracket K at Kis notched 'at e to securely locate the spring D at the end.l 4.The iisu'al c o'vering-rings and chain I are'secured to the rear of the boots F, and it is needless to repress-wheels might be utilized in the same relation.

v Idesire to state in this connection that my improved adjustingfbr'ackets J could be used with other stylesoff drag-bar foradjusting the ten'sion'ont'he spring.' I also desire to state th'etbr makig 'the' disks eed their comme* tiefe' f ,Slifleelt Weigh'E theePfeg-ueeeue might be dispensed with, though I prefer to utilize Athe Siefegfpfeeeure with esi light 'e @meewegen as is ,consistent with .the 'proper strength ofthe disks and hangers.
